The MikroTik CRS112-8P-4S-IN is a versatile cloud router switch designed to handle both routing and switching tasks in a single compact device. It features eight Gigabit Ethernet ports that support auto-sensing 802.3af/at PoE/PoE+ and Passive PoE, allowing you to power connected devices like cameras or access points directly through the network cable. For high-speed uplinks or fiber connections, the unit includes four 1.25G SFP cages, while a dedicated RJ45 console port simplifies initial configuration and management. Inside its white desktop chassis, the device is powered by a 400MHz CPU and 128MB of RAM, running the comprehensive RouterOS L5 operating system. To ensure stability, it includes a PCB temperature monitor and a physical reset button. The hardware is designed for flexibility with dual power inputs supporting either 18-28V or 48-57V DC, which determines the available PoE current limit per port. Measuring 200 x 142 x 44 mm and weighing 500 g, this switch fits easily into small office environments or home labs where reliable power delivery and flexible networking are needed.
